12 Times An Actor Played The Hero And The Villain In The Same Movie

List Rules
Vote up the actors who pulled off good and evil at the same time.

The only thing better than landing one role in a major Hollywood production is landing two. It may seem odd, at first thought, that someone could or would play two roles in the same movie, but it actually happens pretty frequently. The phenomenon is especially common in comedies, where leading character actors fresh off Saturday Night Live tenures are anxious to show off their various silly voices on the big screen. 

Sometimes actors will play their own twin, other times actors will play multiple small roles, yet at other times an actor will hog all the screen time and play the film's protagonist and antagonist simultaneously. While pulling off double duty to this degree takes a lot of work and talent, actors like Mike Myers and Kristen Wiig have performed this stunt to great effect.
